REAL-TIME IOT AND GPS ASSISTED WOMEN SAFTEY DEVICE WITH EMERGENCY ALERTS

Abstract

Women safety remains a critical concern in today's society, where incidents of violence and harassment demand immediate and reliable technological intervention. This project presents a real-time IoT and GPS-assisted women safety device designed to provide immediate emergency alerts through an integrated multi-sensor wearable system. The device incorporates an ESP-32 microcontroller as the processing core, supported by an ESP-CAM for visual surveillance, a DHT11 sensor for environmental monitoring, an SPO2 sensor for vital health data, a panic button for manual emergency triggering, a GPS module for precise location tracking, and a vibration sensor for detecting physical disturbances. All sensor data is processed by the ESP-32, encoded, and transmitted wirelessly via Zigbee communication to a remote receiver station. At the receiver end, a second ESP-32 decodes the transmitted data and activates alert mechanisms including an LCD display, a buzzer for audible alarms, and an IoT cloud interface for remote monitoring and logging. A regulated power supply (RPS) ensures stable operation of both transmitter and receiver units. The system is designed to be compact, lowpower, and cost-effective, providing women with a reliable personal safety solution that bridges wearable electronics with cloud connectivity
